Mission 15: Downfall

1. This is the last level of the game. Listen to Reznov's speech, then follow the troops through the wrecked hallways of the Reichstag, until you reach a massive blockade.
2. First, grab the PPSh-41 from along the Russian cover. Move to the right and launch a Molotov cocktail into the enclosed barricade across the way. Pick off surrounding soldiers with your SVT-40.
3. When reinforcements arrive at the barricade, hit it with another Molotov, then go into the broken wall to your right. Move forward, and then to the left, so you're facing the inside of the German blockade.
4. Flank any soldiers left on the floor and move to the stairway. Use the wall of the second floor as a blind spot where the enemies can't see you, and carefully emerge from that area to shoot the enemies on the stairs.
5. Head upstairs and shoot any remaining enemies. Swap your PPSh-41 for the STG-44, of which there is more ammo on the ground.
6. Checkpoint Reached
7. Shoot the few enemies around the corner to the right, then head down the hall.
8. Death Card: At the next left turn, you'll see a Russian soldier killing a German soldier in a barricaded room ahead. Turn around the corner and go down the short hallway, then look to your right for the doorway into that room. The "Two of Spades" is in the corner directly ahead. If you've taken all the Death Cards so far, this will earn you the Grave Robber Achievement.
9. Checkpoint Reached
10. You'll reach the Parliament, where a massive standoff is taking place. Turn right and you'll see a small room with stairs inside. Climb this to the balcony, where a PTRS-41 is resting against the railing to your left.
11. This area is too far from the enemy for sniping. Follow Reznov to the right along the balcony. Go as far right as you can without losing your vantage point on the stage.
12. Start by shooting the machine gunner in the back center of the stage. Then shoot the two snipers on either side.
13. A Panzerschrek-wielding enemy will appear on the far side of the stage. Dodge his rocket and pick him off. There's also another soldier with this weapon in the middle rows of the theater. Take him down, and keep an eye out for a reinforcement on the stage.
14. Once the Panzerschrek launchers are dealt with, help your comrades below by shooting any German soldiers left standing in the middle of the theater.
15. You'll eventually get a new objective, to clear the south balcony -- across the way from you -- of enemies. This is pretty easy. Just don't miss the one between the two narrow columns.
16. Now, you can clear the ground floor of the Parliament. If you run out of ammo, there's a fresh supply on the far right corner of the balcony. When you see the flamethrowers, shoot the fuel tanks on their backs to create an explosion, causing collateral damage. Expend all of your remaining sniper ammo and head downstairs.
17. You may have to do some light fighting here against any lingering soldiers, but your main goal is to get up the stage to the doorway on the left. Follow the map marker there once the coast is clear.
18. Checkpoint Reached
19. Reznov and some comrades will push the door open. Follow them upstairs, where you'll have a shootout on the south balcony. Use the STG-44 to fight the enemy up here. If they are hiding behind wooden cover, shoot it -- your bullets will go straight through.
20. Checkpoint Reached
21. When you get to the top of the stairs, you'll be met with a devastating wall of bullets, rockets and grenades. Start by moving up the stairs to a small lip on the left entranceway into the clearing. This will serve as your first piece of cover.
22. Before you get out of cover, start lighting a Molotov cocktail, then duck out and launch it at the barricade around the corner to your left. Hide again quickly or you'll be shot to death. Don't worry about whether it was a good shot.
23. Repeat this process once more, for good measure.
24. Storm this barricade, shooting any soldiers behind it as you go. When you reach it, lay prone and wait to heal. Then, sneak around the corner to the left and shoot any soldiers waiting behind it.
25. Rush to the dark hallway in front of you, turn right and shoot the soldiers inside. You're relatively safe here, so reload and catch your breath before your next move.
26. Through the other exit from the passage, you can see a wood-framed structure in the distance with one soldier inside. He's not a major threat, but deal with him to avoid any future issues.
27. Also in this area is a set of thick pipes, through which you can see another hallway filled with German soldiers. Get close to the pipes and stick your STG-44 through to shoot the opposing force. You can also toss grenades through this opening.
28. Once these soldiers are dealt with, turn your attention to the threats outside. An occasional German soldier will step out into the open, but your main target is a machine gun in a tower along the wall of the passage you're in. Get a clear view and fire a series of shots with a rifle (there's a Gehwehr inside the hallway if you need it).
29. Move ahead to the next hallway once the machine gunner is defeated. Pass through the hallway and meet with your comrades on the other side. Your comrade carrying the Russian flag is killed, and it will be your job to carry the flag to the rooftop.
30. Checkpoint Reached
31. Hold X to pick the flag up from where it lays, just before the rooftop opening, Run towards the Nazi flag, to the point where one last German soldier is waiting in ambush.
32. You'll be shot, but by holding X, and moving forward, you can make one last push toward the flag. Stick it in the ground and feel the pride of victory. You just beat Call of Duty: World at War!
